Reese's Peanut Butter Cups

When people from the office here go to Canada, they traditionally bring back a large bag of Reese's Peanut Butter Cups. Eating these things always disturbs me a bit, and I have just worked out why: I can never tell, as I bite into them, whether I have removed the wrapper or not. I don't care what you do to chocolate, but it should be impossible to give it that texture.
